This document discusses databases and their components and functions. It explains that databases are used to store, organize, and manage data and provide access to it for users. The key components of a database management system include the DDL and DML compilers, data manager, data dictionary, and end users. Database administrators work to design, implement, and secure databases and establish policies. A database can contain multiple tables to organize different types of data. Microsoft Access is one program used to create databases and perform common operations on data like adding, editing, deleting, and organizing records. The database design process involves determining requirements, dividing data into tables, specifying keys, and normalizing the structure.

2.  Data is a vital part of any organization. It needs to be stored,
organized, managed, accessed, protected, and manipulated.
 Databases are used to:
 Create a book
 Track book sales
 Set salaries and wages
 Pay employees

3.  Interface between the user and the database.
 User requests the DBMS to perform various operations –
insert, delete, update, and retrieval.
 Components of DBMS perform the requested operations on
the database and provide necessary data to the users.
 Components of database are – DDL Compiler, DML Compiler
and Query optimizer, Data Manager, Data Dictionary, Data
Files, Compiled DML, and End Users.

4.  Works with programmers and analysts to design and
implement the database
 Work with users and managers to establish database policies
 Implements security features and establishes database
permissions

5.  A computerized database is a container of objects.
 One database can contain more than one table.
 For example, an inventory tracking system that uses three
tables is not three databases, but one database that contains
three tables.
 Databases created in the Access format have the file extension
.accdb, and databases created in earlier Access formats have
the file extension .mdb.

6.  Using Access, you can:
 Add new data to a database, such as a new item in an
inventory
 Edit existing data in the database, such as changing the
current location of an item
 Delete information, perhaps if an item is sold or discarded
 Organize and view the data in different ways
 Share the data with others via reports, e-mail messages, an
intranet , or the Internet

Access

7.  Process of producing detailed data model.
 Term can be used to describe many different parts of the
design of an overall database system.
 Design process includes:
 Determine the purpose of the database
 Find and organize the information required
 Divide the information into tables
 Turn information items into columns
 Specify primary keys
 Set up the table relationships
 Refine the design
 Apply the normalization rules
